Erin Hoy
Erin has been involved in either creating vegetation maps or working on Accuracy Assessment for mapping products for more than 15 years. She has worked on many mapping projects, including mapping the Upper Mississippi River floodplain under the Long Term Resources Monitoring Element funded by the US Army Corps of Engineers and the mapping or accurcay assessment elements of many National Parks through the National Parks Vegetation Monitoring Program (VMP). She has also worked on a number of vegetation maps for National Wildlife Refuges throughout the midwest.

Remnant hardwood forest mapping within the Upper Mississippi River Floodplain
Executive SummaryThe primary objective of the project was to locate previously unknown stands of mast-producing hardwood forest trees in the Upper Mississippi River floodplain using existing information. We located and mapped 399 previously unknown hardwood forest stands within the Mississippi River floodplain area of navigation pools 9, 10, and...
